GREY FRAME

A frame accompanying the panel is the last element of the System +. It gives the possibility to arrange the whole ventilated space in the same style without the need to install a fan. Where a mechanical ventilation is required, the user installs a fan, while when it is not needed, the user can install a ventilation grille with the same appearance by using a mounting frame and a fan front. The frame size is 14 cm to 14 cm, which is the most popular size of ventilation grilles in Poland.
